Figure 5. Refrigerant capacity of NiFeCoCr₁Pd_x for select Pd contents: x = 0% (squares), x = 2.91% (circles) and x = 5.88% (triangles), in both the as-rolled (open) and annealed states (closed).

Lines are power law fits. The insert shows RC for ΔH = 50 kOe for the series of samples under both heat treatments.
